Half or full zip? Got S in the 1/2 sip and M in the full zip and there is very little difference. Both are super similar to the Lululemon scuba hoodie but from Amazon! Actually everything is from Amazon! I sized up to M in these camo joggers for a bit more length, small fit me too but were a bit short in the waist and also up to M in the sports bra/tank which I recommend cause I’m only an A cup although it is very stretchy. Socks and sneakers fit tts. LTKunder50 LTKstyletip LTKshoecrush
